1. Structural Principle of Aluminum Foil Laminated Composite Packaging Bags
Deconstruct the multi-layer structure of aluminum foil laminated composite Packaging Bags, including outer protective film, middle aluminum foil barrier layer, and inner heat-seal layer. Explain how the dense metal texture of aluminum foil composite layers forms a zero-permeation barrier. Differentiate aluminum foil laminated composite bags from ordinary plastic composite packaging in barrier performance and protection capability.
2. Core Barrier Performance of Foil Composite Packaging Against Moisture & Oxygen
Quantify the ultra-low OTR and MVTR indicators of aluminum foil laminated composite Packaging Bags. Elaborate on how foil composite packaging completely isolates external oxygen and moisture to prevent product oxidation, damp mildew, and quality deterioration. Supplement additional advantages of foil composite bags such as light shielding and chemical corrosion resistance.
3. Typical Applications & Usage Notes of Aluminum Foil Composite Packaging
List high-demand application scenarios of aluminum foil laminated composite packaging bags, including dried food, pharmaceutical products, electronic components, and premium snacks. Explain product matching rules for different thicknesses of foil composite packaging. Summarize storage and processing precautions to maintain the long-term barrier performance of foil composite packaging bags.
